Spezifische Merkmale von ELASTOSIL® R 570/70 OH

  • elektrisch leitfähig

Control elements for cable accessories, contacts and keypads, interconnectors, electrically conductive rollers, electrodes.

The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous  incorporation is a must, but please avoid temperatures >30°C along the incorporation process in order to maintain best processing behavior. Pot life is depending on the used peroxide and storage condition.      



IMPORTANT: in order to produce a ready-to-use-compound, an increased concentration of peroxide is needed.
ELASTOSIL® R 570/70 OH can be crosslinked with 3.0 % crosslinker C1 or crosslinker C6. Crosslinker E is not suitable!
